This problem only happens with applications using IOCP. It has primarily been seen with Lotus Domino Server. . In certain timing, when the application is sending data and the server abruptly closes the connection, the system can crash. .

Problem summary
An assert is hit with the following stack: F1000000C0277534 iocp.ext:iocp_insque+000014 (F1000E000577D0E0, F1000000C0280A08 ?? ) F1000000C0275470 iocp.ext:iocp_process_pending_io+000270 (??) F1000000C0277C70 iocp.ext:iocp_isr+000070 () 00014D70 .hkey_legacy_gate+00004C () 004A11B8 Netintr+0002F8 () 004A0E80 netisr_thread+000020 () 00255654 threadentry+000094 (??, ??, ??, ??) This happens if the IOCP server closes the connection when the client is still sending the data.
Problem conclusion
Added a check in the IOCP code to avoid the assert.
